Evaluation of data captured by UAV
Martináková, Veronika ; Setnický, Viktor (referee) ; Kalvoda, Petr (advisor)
The master´s thesis deals with the application of unmanned aerial vehicle (UAV) in photogrammetry and mapping. The first part describes the UAV that was used for imaging, legislative restrictions resulting from its operations, planning and realization of the flight. The second part of this thesis is focused on processing results, especially on evaluation the accuracy of the results gained by UAV with and without a GNSS module. The data are evaluated in the 3rd accuracy rating class (ČSN 01 3410). The theoretical principles are explained as well. The main aim of the thesis is to demonstrate the effective use of the GNSS module Emlid Reach and the unmanned aerial vehicle in geodesy.

Flight Trajectory Planning for Unmanned Aerial Vehicles
Horeličan, Tomáš ; Jílek, Tomáš (referee) ; Gábrlík, Petr (advisor)
This thesis deals with the problem of planning a complete flight trajectory (ie. horizontal and vertical components) for unmanned aerial vehicles (UAV) with a main focus on maintaining a constant height and distance from the terrain. It includes the design of the trajectory planner itself, which is created in the Matlab environment. The design is mainly focused on small rotary aerial vehicles and drones. Main concepts of geolocation are discussed in the first chapters, which includes means of realization, basic terminology and theory that is needed in order to sufficiently track an object and its height on Earth. Principles of aerial survey, its use cases and means used in this thesis are also described. Following chapters present a complete hierarchical overview of the functionality of the designed planner and provide demonstrations with simulations. The practical part discusses results obtained from real flights of the vehicle.

Traffic Monitoring from Aerial Video Data
Babinec, Adam ; Orság, Filip (referee) ; Rozman, Jaroslav (advisor)
This thesis proposes a system for extraction of vehicle trajectories from aerial video data for traffic analysis. The system is designed to analyse video sequence of a single traffic scene captured by an action camera mounted on an arbitrary UAV flying at the altitudes of approximately 150 m. Each video frame is geo-registered using visual correspondence of extracted ORB features. For the detection of vehicles, MB-LBP classifier cascade is deployed, with additional step of pre-filtering of detection candidates based on movement and scene context. Multi-object tracking is achieved by Bayesian bootstrap filter with an aid of the detection algorithm. The performance of the system was evaluated on three extensively annotated datasets. The results show that on the average, 92% of all extracted trajectories are corresponding to the reality. The system is already being used in the research to aid the process of design and analysis of road infrastructures.

Design of a quadcopter model
Fiala, Jan ; Dosoudilová, Monika (referee) ; Hůlka, Tomáš (advisor)
The bachelor thesis deals with the creation and implementation of a quadcopter model. The first part summarizes the basic division of unmanned systems and the rules of legislation limiting their operation. Subsequently, the problematics of motion dynamic is discussed. The practical part first describes the selection of components used, their connection, and the creation of the quadcopter frame. The implemented control system and calibration are also described. In the final part, a flight test, price analysis, and rating in comparison with the competitive product are included. The conclusion contains an evaluation of the work, possible improvements, and reflections on the future use of the model.

Performance possibilities of VTOL Unmanned Aerial Vehicle
Bartlová, Tereza ; Matějů, Jiří (referee) ; Juračka, Jaroslav (advisor)
Tato bakalářská práce popisuje a vyhodnocuje výkonnosti bezpilotních leteckých prostředků se svislým vzletem a přistáním pro transport nákladu. První část práce popisuje problém v oblasti transportu nákladu a současně nastiňuje možné řešení tohoto problému pomocí bezpilotního leteckého prostředku. Dále je definována mise, kterou bezpilotní prostředek musí splnit, a podle této mise specifikuje výkonnostní požadavky na bezpilotní prostředek. V této části je rovněž krátce zmíněna problematika legislativy provozování dronů v Evropské Unii. Druhá část této práce se zabývá analýzami, pomocí kterých jsou posouzeny výkonnostní požadavky a odhad potřebného výkonu bezpilotního letadla pro splnění požadované mise. První analýza je založená na datech o letových výkonech existujících bezpilotních i pilotních letadlech. Druhá analýza se zabývá vztahem mezi výkonem a celkovou plochou vrtulí. Další analýza se zabývá vztahem mezi maximální vzletovou hmotností a celkovou plochou vrtulí. Na závěr je prověřen vliv různých konfigurací letadla se svislým vzletem a přistáním na potřebný výkon a celkovou plochu vrtulí. Třetí část této práce je zpracován prvotní konfigurační návrh bezpilotního prostředku se svislým vzletem a přistáním, s tandemovým uspořádáním otáčivých křídel osazených pohonnými jednotkami. Nejprve je pro tuto konfiguraci vybrán počet vrtulí a jejich průměr a také odhadnut potřebný výkon. Poté je popsán prvotní návrh hybridní pohonné soustavy. Následně je provedena hmotnostní analýza prvotního konfiguračního návrhu bezpilotního prostředku s hybridním pohonem. Na závěr po zhodnocení výsledků všech analýz, je prezentován výkres hrubého konfiguračního návrhu bezpilotního prostředku.

Aerial platform built on operating system FlytOS
Širjov, Jakub ; Štůsek, Martin (referee) ; Pokorný, Jiří (advisor)
The aim of this bachelor's work is creation of functional model of flying platform that can carry additional devices. The platform is designed to maintain continuous connection with the base station and to create an access point for a particular area. The flying platform has FlyOS installed, which facilitates control of the flying platform. Another part of the work describes steps for simulation of the first automated flight in FlytSIM with a preset parameter of rotation during flight. The platform's functionality is then verified by using manual remote control and also by simulated automated flight in real conditions. Final part shifts attention to the algorithm used for the computation of the rotation of the flight waypoints direction in degrees towards the base station based on the input data. In the case of large distances between the flight waypoints, it computes coordinates and the rotation of the UAV.
